Casting remains historically faithful, featuring predominantly white British/Irish/Romani actors like Cillian Murphy, Paul Anderson, and Helen McCrory, with ethnic rivals such as Jewish gang leader Alfie Solomons (Tom Hardy) and Italian Darby Sabini perfectly suiting the era's criminal landscape—no race-swapping, gender alterations, or DEI-mandated diversity clashes. Strong female characters like Polly Gray and Ada Shelby exhibit toughness and agency integral to their roles in a patriarchal gangster world, but this feels organic rather than forced feminist messaging.

Subtle period elements, such as Ada's brief socialist ties via Freddie Thorne or Polly's traumatic abortion backstory, are plot devices rooted in 1920s historical realities (labor unrest, illegal abortions) and do not dominate or lecture on systemic injustices. Creator Steven Knight emphasizes working-class authenticity without activist intent, and reception lacks any 'woke' backlash, confirming the season's pure focus on riveting storytelling over contemporary politics.
